I hit the magnifying glass and it went back to posts
After the update it wont switch back.
I'm having the same problem
All it says is question it doesn't have a post choice😐
When you click on the "?" on the middle bottom bar, it should pop up with a "post" option on the left and the "question" on the right. Click the question when you want to post the question and the post when you want to switch back!
If you click the plus button at the bottom of the screen it should give you an option to post or ask a question.
